Photo Sweeper

If you have multiple duplicates in your photo library or you take multiple photos of almost exactly the same picture trying to get the best one, Photo Sweeper can help you eliminate duplicates and choose between almost identical photos quickly and easily. It will also help eliminate duplicate files and folders to clean up your desktop and hard drives. Works on your phone also.

You can let the program automatically eliminate duplicates for you or have it mark them for you to look at and duplicate. It is so effective, I learned to just let it automatically eliminate my duplicates.
